60 miles an hour for 45 minutes = 45 miles
50 miles per hour for 30 minutes = 25 miles
Total =70 miles
Answer:

Step-by-step explanation:
Step 1: Write expression

Step 2: Simplify Parenthesis

Step 3: Exponent Exponents

Step 4: Simplify

So, here you have to look at the periodic table and see what the molar mass of each molecule composing the water compound

its two hydrogen atom plus an oxygen molecule, making it about 18g per mol.
That said, looking at the mass, we have to ask ourselves, if a mol of water contains 18g of mass, how many moles do we have in 0.5g of water?
We just do a cross multiplication:
Explanation:
The formula isnt correctly written, it should state:

You have to start from
and end in a³+b³. On your first step, you need to use the distributive property.

This is equal to

Note that the second term, -a²b, is cancelled by the fourth term, ba², and the third term, ab², is cancelled by the fifht term, -b²a. Therefore, the final result is a³+b³, as we wanted to.
Here is a set of 5 numbers that give a mean of 17.25.
Answer:
14, 11, 16, 21, 24.25
